Thanks for making this available.
A couple of notes:
Here is the path stuff I setup up:
:: Dingo OpenDingux SDK change start
:: Dingo OpenDingux SDK
:: NOTE has to live in /opt (no idea why, that's what everyone says, apparently it fails)
:: Dingo SDK change end
With DINGUX_SDK set you can use r366 http://code.google.com/p/dingoo-sdk/source/detail?r=366
to build one of the Native SDK Hello World apps for OpenDingux.
Extracting the tarball can NOT be done with a GUI (like 7z) as the tar contains soft-links, instead open up the Cygwin window and install via:
cd / ; mkdir opt ; cd opt
tar -xvvf ../opendingux-toolchain-cygwin.2012-06-16.tar
I did hit an issue with one (complex) file where the compiler couldn't handle -O2 (-01 worked) and gcc ran out of memory, I do not get this with Linux toolchain.
